So I was working late last night when it hit me, I had shut down all the pumps in my tank the night before for maintenance and had forgotten to turn them back on the next morning! It had been about 22 hours since there was any water movement in my tank. Of course I couldn't reach my wife by phone so I quickly wrapped up what I was working and sped code 3 all the way home. I nearly knocked my wife over racing to the tank since I figured I killed every last fish in the tank. The powder blue tang looked a little stressed, but everyone survived without a scratch.

Anyone else ever have a moment terror like I did? What sort of fish tank fail did you cause and how long did it take you to realize your mistake?
